Power Tools

Today I was brushing up my stats a little so I can halfassed intelligently discuss the power analysis in my proposal. Along the way I found some online calculators for power (and a lot of other nassssty statistically things). The best of the bunch (<--read: nearly math ree-tard proof) can be found here:

Russ Lenth's statistical power & sample size applets

Power Analysis for ANOVA Designs

Statistical Calculators

Links through Hyperstat

My brain is way past tired. Just thought I'd share.
